Description

Technical Field

[0001] The present application relates to the technical field of mounting connectors, and in particular to a fixing structure of a liquid cooling unit. Background Art

[0002] With the rapid development of industrial and commercial energy storage technology, efficient and stable energy storage systems have become an urgent need of the industry. In this process, PCS (power conversion system) cooling technology has gradually become a core component of industrial and commercial energy storage systems due to its efficient cooling effect. In particular, liquid cooling technology has a much higher cooling efficiency than traditional air cooling technology. Therefore, PCS liquid cooling units have gradually become the mainstream choice of the industry.

[0003] However, in the actual application of industrial and commercial energy storage systems, the fixing method of the PCS liquid cooling unit and the cabinet has become a key issue that needs to be solved. In the existing fixing method, the frame and the fixed bracket of the PCS liquid cooling unit are usually welded together. When the unit frame and the cabinet are assembled, this fixing method causes an assembly gap between the two due to the existence of the processing tolerance of the fixed bracket and the cabinet. Such a gap makes the connection between the unit frame, the fixed bracket and the cabinet unreliable. During the transportation of the cabinet, the unit will shake because the internal PCS liquid cooling unit is not firmly fixed. This shaking will not only affect the stable operation of the unit, but may also cause the water channel docking interface on the unit to loosen. Once the docking interface is loose, it may cause the risk of leakage, posing a serious threat to the safe and stable operation of the energy storage system.

[0004] In view of the above problems, it is necessary to develop a new fixing method that can improve the reliability of the fixing of the unit and the cabinet, so as to solve the problems existing in the existing fixing method and improve the safety and stability of the liquid cooling unit.

[0006] The present application provides a fixing structure of a liquid cooling unit, comprising a cabinet, a unit frame and a fixing bracket; the fixing bracket comprises a first fixing plate and a second fixing plate arranged at right angles;

[0007] The first fixing plate is used for fitting and connecting with the cabinet; the second fixing plate is provided with at least one waist-shaped hole, the extension direction of the waist-shaped hole is the same as the width direction of the unit frame, and the length of the waist-shaped hole is smaller than the width of the unit frame.

[0008] Furthermore, at least one connecting hole is provided on the first fixing plate, and the first fixing plate is fixedly connected to the cabinet through the connecting hole.

[0009] Furthermore, the connection hole is a circular through hole, and a distance L1 from a center point of the connection hole to a junction line where the first fixing plate and the second fixing plate are connected is 25-35 mm.

[0010] Furthermore, the length of the waist-shaped hole is L2, and the range of L2 is 20-40 mm.

[0011] Furthermore, a locking hole matching with the waist-shaped hole is provided in the middle of the unit frame.

[0012] Furthermore, a distance L3 from the center point of the waist-shaped hole to the intersection line where the first fixing plate and the second fixing plate are connected is 30-40 mm.

[0013] Furthermore, the fixing bracket is formed by stamping a steel plate with a thickness of 2-5 mm.

[0014] Furthermore, the fixing bracket includes at least one reinforcing plate, one side of the reinforcing plate is connected to a side of the first fixing plate, and the other side of the reinforcing plate is connected to a side of the second fixing plate.

[0015] Furthermore, the reinforcing plate is a triangular or rectangular connecting plate.

[0027] Example 1

[0028] Embodiment 1 of the present application provides a fixing structure of a liquid cooling unit, including a cabinet 1, a unit frame 2 and a fixing bracket 3. The unit frame 1 is fixedly connected to the cabinet 1 through the fixing bracket 3. The liquid cooling unit includes a liquid cooling pipeline 4, and the liquid cooling pipeline 4 includes a plurality of pipeline docking ports 41. When the fixing bracket 3 and the cabinet 1 cannot be completely fitted and fixed, the fasteners between the fixing bracket 3 and the unit frame 2 and the cabinet 1 cannot be completely fastened. During transportation, the liquid cooling unit may easily shake, thereby causing the risk of loosening or leakage of the pipeline docking ports of the liquid cooling unit.

[0029] In view of the above problems, the present application provides a fixing structure of a liquid cooling unit, which is combined with Figure 1-Figure 3 The present invention provides a fixing structure of a liquid cooling unit. Figure 1 It is a structural diagram of a fixed structure. Figure 2 Schematic diagram of the structure of the connection between the fixed bracket and the unit frame.

[0030] The fixing bracket 3 of the embodiment of the present application includes a first fixing plate 31 and a second fixing plate 32 arranged at right angles. The first fixing plate 31 is used to fit and connect with the cabinet 1. The second fixing plate 32 is provided with at least one waist-shaped hole 321, and the extension direction of the waist-shaped hole 321 is the same as the width direction of the unit frame 2, and the length of the waist-shaped hole 321 is less than the width of the unit frame 2.

[0031] In the embodiment of the present application, a waist-shaped hole 321 is provided on the second fixing plate 32, so that the fixing bracket 3 can flexibly adapt to the width change of the unit frame 2 during installation and positioning. The design of the waist-shaped hole 321 also helps to optimize the force distribution between the fixing bracket 3 and the unit frame 2. When subjected to external force, the waist-shaped hole 321 can disperse and transmit force more evenly, reduce the risk of stress concentration and damage, and thus extend the service life of the fixing bracket 3 and the unit frame 2. The length of the waist-shaped hole 321 is less than the width of the unit frame 2, so that the size matching between the fixing bracket 3 and the unit frame 2 is more reliable, the connection is tighter and more stable, and the safety hazards caused by loose connection or misalignment can be reduced, and the stability and reliability of the entire system can be improved. Through the adjustment effect of the waist-shaped hole 321, the present application can adjust the position of the fixing bracket 3 to achieve a close fit between the fixing bracket 3 and the cabinet 1, even if there is a processing tolerance between the cabinet 1 and the fixing bracket 2, thereby improving the fixing effect, reducing the shaking of the liquid cooling unit during transportation, and reducing the risk of leakage.

[0032] In some possible implementations, the fixing bracket 3 is an L-shaped bracket, wherein the length of the first fixing plate 31 is smaller than the length of the second fixing plate 32 .

[0033] Specifically, at least one connecting hole 311 is provided on the first fixing plate 31, and the first fixing plate 31 is fixedly connected to the cabinet 1 through the connecting hole 311. The cabinet 1 is provided with a cabinet matching hole that matches the connecting hole 311. The fixing structure of the embodiment of the present application is fixedly connected to the cabinet 1 through fasteners including but not limited to bolts, screws, studs, etc. passing through the connecting hole 311. The provision of the connecting hole 311 makes the connection between the first fixing plate 31 and the cabinet 1 more convenient and stable, and improves the stability of the overall structure. In the embodiment of the present application, one connecting hole 311 is provided on the first fixing plate 31. In some possible embodiments, two or more connecting holes 311 may be provided on the first fixing plate 31.

[0034] Specifically, the connection hole 311 is a circular through hole, and the distance L1 from the center point of the connection hole 311 to the intersection line where the first fixing plate 31 and the second fixing plate 32 are connected is 25-35 mm. In some possible embodiments, the distance from the center point of the connection hole 311 to the intersection line can be 25 mm, 26 mm, 28 mm, 30 mm, 32 mm, 33 mm, 34 mm or 35 mm. By reasonably setting the distance range from the center point of the connection hole to the intersection line, the embodiment of the present application can ensure that the position of the connection hole 311 is neither too close to the intersection line to cause insufficient strength, nor too far away from the intersection line to make the connection unstable, thereby achieving a balance between the structural strength and stability of the fixed bracket 3.

[0035] Specifically, the length of the waist-shaped hole 321 is L2, and the range of L2 is 20-40mm. In some possible embodiments, the length L2 of the waist-shaped hole 321 can be 20mm, 24mm, 25mm, 28mm, 30mm, 33mm, 36mm, 38mm or 40mm. In some possible embodiments, the length L2 of the waist-shaped hole 321 is set according to the width of the unit frame 2. The length range of the waist-shaped hole in the embodiment of the present application can not only meet the adjustment requirements of the assembly gap between the fixed bracket 3 and the cabinet 1, but also ensure the overall strength of the fixed bracket 3, and avoid the problem of reduced structural strength and easy loosening caused by the waist-shaped hole 321 being too long. Preferably, the length L2 of the waist-shaped hole 321 is 24mm. When the length of the waist-shaped hole 321 is set to 24mm, this specific size can not only meet the variation range of the width of the unit frame, but also ensure the strength and stability of the fixed bracket.

[0036] Specifically, a locking hole is provided in the middle of the unit frame 2 to cooperate with the waist-shaped hole 321. In the embodiment of the present application, fasteners including but not limited to bolts, screws, studs, etc. are passed through the waist-shaped hole 321 and the locking hole to connect the fixing bracket 3 and the unit frame 2. Due to the setting of the waist-shaped hole 321, the fixing bracket 3 can be adjusted in the width direction of the unit frame 2 before fastening. Figure 2 The arrow direction in the structural schematic diagram of the connection between the fixed bracket and the unit frame is the movable direction of the fixed bracket.

[0037] Specifically, the distance L3 from the center point of the waist-shaped hole 321 to the intersection line where the first fixing plate 31 and the second fixing plate 32 are connected is 30-40 mm. In some possible embodiments, the distance from the center point of the waist-shaped hole to the intersection line can be 30 mm, 32 mm, 34 mm, 35 mm, 36 mm, 38 mm or 40 mm. By reasonably setting the distance range from the center point of the waist-shaped hole to the intersection line, the embodiment of the present application can ensure that the position of the waist-shaped hole 321 can not only meet the adjustment requirements of the assembly gap between the fixed bracket 3 and the cabinet 1, but also maintain the structural strength and stability of the fixed bracket 3.

[0038] Specifically, the fixing bracket 3 is stamped and formed by a 2-5 mm thick steel plate. In some possible implementations, the fixing bracket 3 can be stamped and formed by a 2-3 mm thick steel plate; preferably, the thickness of the fixing bracket 3 is 2.5 mm. The embodiment of the present application selects a 2-5 mm thick steel plate as the material of the fixing bracket, which not only ensures sufficient strength and stability, but also controls costs, achieving a balance between economy and practicality.

[0039] In the embodiment of the present application, the fixing bracket includes a first fixing plate and a second fixing plate arranged at right angles, the first fixing plate is used to fit and connect with the cabinet; the second fixing plate is provided with at least one waist-shaped hole, the extension direction of the waist-shaped hole is the same as the width direction of the unit frame, and the length of the waist-shaped hole is less than the width of the unit frame. The setting of the waist-shaped hole allows the fixing bracket to be moved and adjusted in the length direction of the waist-shaped hole, so that the fixing bracket can be seamlessly fitted and connected with the cabinet to avoid assembly gaps, and at the same time, the fixing between the unit frame and the cabinet is tighter and more reliable, and during the transportation of the cabinet, the liquid cooling unit inside the cabinet will not shake.

[0041] Embodiment 2 of the present application provides a fixing structure of a liquid cooling unit. Embodiment 2 differs from Embodiment 1 in that:

[0042] In the embodiment of the present application, the fixing bracket 3 includes at least one reinforcing plate, one side of the reinforcing plate is connected to the side of the first fixing plate 31, and the other side of the reinforcing plate is connected to the side of the second fixing plate 32. In some possible implementations, the fixing bracket 3 includes two oppositely arranged reinforcing plates, and the two reinforcing plates are respectively connected to the side of the second fixing plate 32 on both sides of the waist-shaped hole 321. The provision of the reinforcing plate in the embodiment 2 of the present application can significantly improve the overall strength and stability of the fixing bracket 3, especially when the unit frame 2 is wider or the cabinet 1 is heavier, the role of the reinforcing plate is more obvious.

[0043] Specifically, the reinforcing plate may be a triangular or rectangular connecting plate. In some possible embodiments, the reinforcing plate may be a triangular connecting plate, one right angle side of the triangular connecting plate is connected to the side of the first fixing plate 31, and the other right angle side is connected to the side of the second fixing plate 32. In some other possible embodiments, the reinforcing plate may be a rectangular connecting plate. The embodiment of the present application adopts a triangular or rectangular connecting plate as a reinforcing plate, which has a simple structure, high strength, and is easy to manufacture, and can effectively improve the bearing capacity and stability of the fixing bracket.

[0044] Specifically, the first fixing plate 31, the second fixing plate 32 and the reinforcing plate are integrally formed. The design of the first fixing plate, the second fixing plate and the reinforcing plate integrally formed in the embodiment of the present application not only simplifies the manufacturing and installation process, improves production efficiency, but also further enhances the stability and reliability of the overall structure.

[0045] In the embodiment of the present application, the fixing bracket can be adjusted in the width direction of the unit frame, while further improving the overall strength and stability of the fixing bracket, and improving the tightness and reliability of the connection between the unit frame and the cabinet, so that the fixing bracket can be seamlessly connected to the cabinet to avoid assembly gaps, and at the same time, the fixation between the unit frame and the cabinet is tighter and more reliable, and during the transportation of the cabinet, the liquid cooling unit inside the cabinet will not shake.

[0046] Example 3

[0047] Embodiment 3 of the present application provides a fixing structure of a liquid cooling unit. Embodiment 3 differs from Embodiment 1 in that:

In some possible implementations, the first reinforcement side is connected to the second reinforcement side. The reinforcement side formed by bending in the present application can significantly improve the edge strength of the fixing bracket 3, effectively prevent deformation or damage of the fixing bracket caused by external force, and can greatly enhance the stability and bearing capacity of the fixing bracket.
